A new name in research peptides, landing in the UK
SerenQ Pharmaceuticals builds research peptides into sealed, pre-filled injection pens rather than lyophilised vials. No reconstitution, no bacteriostatic water, no guesswork with a syringe barrel. Dial the units you need, read them off the window, done.
SerenQ has appointed The Ped Shop as its exclusive UK stockist. Every pen sold here comes direct from the manufacturer, in sealed retail cartons, with a unique serial number and QR authenticity code on the label.

Third Party Testing
Every SerenQ batch is sent for independent analysis before it goes on general sale. Purity and identity testing for this batch is currently with Analiza, and the certificate will be published on this page the moment it lands.
Check back here for the full certificate, or ask us and we will send it over as soon as it is released.
Serialised & QR Verified
Every SerenQ product carries a unique serial number and a QR code printed on the label. Scan it with any phone camera and you can independently confirm the pen is genuine SerenQ stock and check its batch details before you open the carton.
One code per pen. Each one can only be registered once, so a duplicate scan is an immediate red flag.

KLOW is the GLOW blend with KPV added. Where GLOW pairs the two tissue repair peptides with a collagen signalling peptide, KLOW brings in a fourth acting specifically on inflammation, which is the variable the other three do not directly address.
The rationale for the combination is that each component covers a different stage of repair. BPC-157 is associated in the literature with angiogenesis and with tendon and gut tissue; TB500 acts on actin regulation, which governs how repairing cells migrate to the site; GHK-Cu is a copper binding tripeptide involved in collagen and elastin synthesis and in extracellular matrix remodelling. KPV, the tripeptide tail of alpha-MSH, damps the inflammatory signalling that runs alongside all of it.
The practical argument for a blend over four separate pens is ratio stability. Four pens drift apart as they empty at different rates and as doses get adjusted independently; a single cartridge fixes the proportions at the factory. The cost is exactly the same thing: you cannot raise one component without raising all four.
The pen format
Four compounds in one cartridge means one injection instead of four and a ratio that cannot drift. Each unit delivers 33mcg each of BPC-157, TB500 and KPV alongside 167mcg of GHK-Cu.
- BPC-157 10.00mg, TB500 10.00mg, KPV 10.00mg, GHK-Cu 50.00mg per pen, pre-combined in one cartridge
- 1 unit = 33mcg / 33mcg / 33mcg / 167mcg respectively
- 300 units in total, so the ratio between the actives is fixed and cannot drift
- Dial and dose window let you set the exact amount and read it back before dispensing
- 4 screw on pen tips supplied, individually sealed, 32G 0.23 x 4mm
- Protective cap, clip and a rigid retail carton for storage and transport
- Batch number, expiry and serial printed directly on the pen barrel, not just the box
Handling and storage
- Store refrigerated at 2 to 8°C. Do not freeze
- Keep in the outer carton, away from direct light
- Short periods at room temperature during transit are expected and normal
- Use a fresh sealed tip for each dispense and dispose of tips in a sharps container
- Expiry 12/2027 on sealed, correctly stored stock
- Keep out of reach of children and animals
What is in the box
- 1 × SerenQ KLOW pre-filled injection pen
- 4 × sealed pen tips, 32G 0.23 x 4mm
- Serialised, QR coded retail carton
Choosing between KLOW, GLOW and the Heal pen
These three are the same idea at three levels of coverage. Heal is the minimum viable version: BPC-157 and TB500 at 5mg each, the repair pairing and nothing else. GLOW doubles both to 10mg and adds 50mg of GHK-Cu, which brings skin and collagen into scope. KLOW is GLOW plus 10mg of KPV, adding the anti-inflammatory component.
Pick on whether inflammation is part of what you are looking at. If it is a straightforward tendon or soft tissue question, GLOW already covers it and KPV is paying for something you are not using. If there is an inflammatory element, KPV is the piece the other two are missing.

Quality pen great packaging. Reasonable price and very quick delivery. My go 2 store for all my products
View on Trustpilot⭐⭐⭐⭐⭐ Excellent service and fast delivery! This was my first time ordering from this company, and I was so pleased with the experience that I ordered from them again. Both times, the delivery was very quick, and the supplements were excellent quality. I’m really happy with the service and products and would happily recommend them. I will definitely order from them again!
View on TrustpilotLoving it so easy to do it is what it says it is so I’m very happy
View on TrustpilotPen work as it should, would be better if you could do 5mg in on dose
View on TrustpilotExcellent service, brilliant results "Customer service was first class. My wife has been using tirzepatide SerenQ and it's been brilliant. She's lost weight, and her mental clarity and physical appearance have improved. It's been amazing to have my happy wife back. Thank you!"
View on TrustpilotThe packaging was excellent and the pen is generally easy to use. However, I feel the injection button mechanism could be improved, as it feels slightly flimsy when pressing down to release the solution. The dial/turning function also feels like it could be made more durable and sturdy. It would be great to see more needle heads included as standard, or alternatively have the option to purchase additional needles directly through your website for convenience. Overall, a good product with some small areas that could be improved to enhance the user experience.
View on TrustpilotI’ll start by saying it works , the delivery was quick and faultless , the pen is easy to use once you get your head round dosing , I will be reordering, and have recommended to friends .
